De Incredibilibus

They say that Caineus was invulnerable. Whoever imagines that a person cannot be wounded by iron is foolish.

The truth is as follows. Caineus was a Thessalian by birth, skilled in military affairs and experienced in fighting. And yet, despite being in many battles, he was never wounded, not even when he died fighting with the Lapiths against the Centaurs. When the Centaurs captured him they merely buried him, and in this way he met his end. The Lapiths dug up his corpse and found no wounds on his body. And so they would say, Caineus was invulnerable his whole life - he even died without a wound.

The same story is also told about Cycnos of Colonai: that he too was invulnerable. He was also a warrior and experienced in battle. He died at Troy after being hit by a stone thrown by Achilles, and yet even then there were no wounds on his body. When they saw his corpse, people would say that he was invulnerable just as now they describe unbeaten athletes combatants as invulnerable. As evidence against these stories and in support of my case, consider Telemonian Aias, for he, too, was said to be invulnerable, and yet he died of a self-inflicted sword wound.
